The NMR system that produced all the spectra on this page costs less than $40,000.
19F NMR analysis is applicable to isomeric
mixtures such as shown in this spectrum of
Peaks marked A are of one of the two isomers.
31 NMR can be used to analyze pesticides and other phosphorus- containing chemicals such as trimethylphosphite (spectrum shown).
1H NMR analysis of acetyl acetone at -19C, +40C, and+100 C shows the temperature dependence of this keto/enol equilibrium.
The multi-nucleus, easy-to-use, under-$40,000,
T-60 NMR spectrometer system. You get back a lot
more than you put in.
